SASH-FASTENER.

Specification of Letters Patent No. 13,491, dated August 28, 1855.

T0 all whom it may concern.'

Be it known that I, AsAHEL GILBERT, Jr., of Lowell, in the county ofMiddlesex and Commonwealth of Massachusetts, have invented certain newand useful Improvements in Sash-Fasteners for Vindows of Railway-.Carsand for All other Kinds of Vindows; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon.

Figure l, is a front elevation of a window sash and its supportingframe, having my improvements attached. Fig. 2 is a vertical sectionthrough w and Fig. 3 is a horizontal section through y, e.

Similar letters of reference in each of the several figures, indicatesimilar parts.

A, is the window frame that supports the sash, and in which, the sashslides up and down.

B, is the sash.

C, C, is the knob or handle by which the sash is raised and lowered.This knob is made of two parts which are connected together and to theface plate D by a hinge joint.

s, s, are two short arms that extend one from each half C, of the handleor knob. When the two halves of the knob are pressed together, thesearms s s, shut by each other like the blades of a pair of scissors.Fastened to the extremity of each of these arms s, s, is a smallconnecting wire E, E. These wires extend out horizontally, one to eachedge of the sash, through a channel made for the purpose in a bar of thesash, and fastened to these extremities are the bolts F, F. These boltsare situated in holes made for them, one in each edge of the sash; andthe end of each projects therefrom a sutlicient length, to enter theholes G G, G, &c., made in the window frame.

H, I-I, are spiral springs, which are placed between the inner ends ofthe bolts and the inner ends of the holes made to receive them, for thepurpose of forcing the bolts into the holes G, G, G, te., in the frame,and thus secure the sash in position.

Having thus described the various parts of which my invention iscomposed, I will proceed to describe their operation.

If the sash is down, and we wish to raise it; all it is necessary to do,is to press the two parts of the knob together with the thumb andlinger, which will draw the bolts and liberate the sash; then lift onthe knob until the sash is raised to its full height, and when you letgo the handle, the springs will force out the bolts vinto the holes G,G, &c., and thus fasten the sash in its elevated position.

It is evident that the window may be fastened at any height by providinga sulicient number of holes in the frame.

Vhat I claim is- The hinged cross-bars C, C, having splitknob handles,serving to disengage the r fastening on both sides of the sash, and toraise and lower the sash, substantially as herein described.

In witness whereof, I have hereunto set my signature this twelfth day ofMay A. D. 1855.
